Question

kaiden and her brother both open savings accounts. each begin with a balance of zero dollars. for every two dollars that kaiden saves in her account, her brother saves five dollars. if kaiden saves 300 dollars how much did her brother save

Answer 1

The ratio is 2:5

• Kaiden saves=300$
• Let her brother saves x

ATQ

`\\ \sf\longmapsto (300)/(x)=(2)/(5)`

`\\ \sf\longmapsto 2x=300(5)`

`\\ \sf\longmapsto 2x=1500`

`\\ \sf\longmapsto x=(1500)/(2)`

`\\ \sf\longmapsto x=750\$`
